  EXAMPLES Next, although an Example demonstrates this invention in detail, this invention is not limited to these Examples. In addition, all compounding quantities are shown by the mass% (henceforth%).

  Based on the formulation shown in Table 1, the mist-like hair cosmetics of Examples 1 to 6 and Comparative Examples 1 to 7 are prepared, and the degree of re-styling, the sensory test, and the solubility test are performed as shown below, and the evaluation results Is also shown in Table 1.

(1) Evaluation of re-hairing degree Apply 2 g of a mist-like hair cosmetic sample evenly to a hair bundle of 25 cm in length and 2 g in weight, wind it around a rod with a diameter of 2 cm, and leave it in a constant temperature room at 45 ° C. for 6 hours. , Completely dried. After drying, the rod was removed and the apparent length (L0) of the hair bundle was measured. Next, the hair bundle was hung in a constant temperature and humidity chamber at a temperature of 25 ° C. and a humidity of 60%, taken out after 30 minutes, wound around the rod again, and dried in a constant temperature and humidity chamber of 25 ° C. and a humidity of 60%. The rod was removed, the hair bundle was suspended in a constant temperature and humidity chamber at 25 ° C. and 60% humidity, and the apparent length (Ln) of the hair bundle was measured. The measurement so far is defined as one cycle. Subsequently, the sample was left for 30 minutes, wound on a rod, re-dried, and the measurement was repeated three times, and the change in the re-styling degree was compared.

The degree of re-styling was obtained by the following formula.
Re-hair setting = (25−Ln) / (25−L0) × 100
Therefore, the closer this value is to 100, the higher the degree of re-styling.

The evaluation criteria are as follows. The fourth degree of re-styling was compared.
◎: Very good re-hairing degree 85% or more ○: Good re-hairing degree 80% or more, less than 85% △: Slightly poor re-hairing degree 70% or more, less than 80% ×: Bad re-hairing degree 70% or less

(2) Sensory test Hair styling was carried out using hair cosmetic samples by 20 subjects. Thereafter, the subject himself / herself performed a sensory evaluation on non-stickiness and gloss.

The evaluation criteria are as follows.
<No stickiness>
◎: The number of subjects who answered that there was no very good stickiness was 18 or more. ○: The number of subjects who answered that there was no good stickiness was 12 or more and less than 18. △: The number of subjects who answered that there was no bad stickiness. Number is 8 or more and less than 12 ×: The number of subjects who answered that there was no bad stickiness was less than 8

<Gloss>
◎: The number of subjects who answered that the gloss was very good was 18 or more. ○: The number of subjects who answered that the gloss was good was 12 or more and less than 18. Δ: Slightly bad The subjects who answered that the gloss was good. Number is 8 or more and less than 12 ×: Bad The number of subjects who answered that gloss is good is less than 8

(3) Solubility test An aerosol spray composition (pressure glass container) prepared by a conventional method is allowed to stand in a thermostatic bath at 0 ° C, 20 ° C and 35 ° C, and the solubility is visually evaluated after 24 hours. did. The evaluation criteria are as follows.

・ Dissolves transparently and uniformly: ○
・ There are turbidity, precipitation, separation, etc .: ×

  As is apparent from Table 1, the mist-like hair cosmetic of the present invention was excellent in all of the re-hair styling property, non-stickiness, unnatural luster and solubility.

  On the other hand, in Comparative Examples 1-7, either characteristic was inferior and the objective of this invention was not able to be achieved.
